I have not found any easy way to accomplish to simply check a Checkbox by default. That can not be that hard, so what am i missing?

Answer

You can also just set the attr attribute in the form builder buildForm method:

$builder->add('isPublic', 'checkbox', array(
    'attr' => array('checked'   => 'checked'),
));
